J3068 was developed in a consensus process by SAE International’s Medium and Heavy Duty Vehicle Conductive Charging Task Force Committee, which today is comprised of over 100 global experts from the automotive industry, utilities, charging equipment manufacturers, national laboratories, and academia.

"This new standard was designed to offer a single vehicle charging coupler solution for three-phase and single-phase AC and DC charging for a class of vehicles," according to Rodney McGee, Chief Engineer of EV Projects, University of Delaware, and SAE Medium and Heavy Duty Vehicle Conductive Charging Task Force Chair. "We wanted to combine this new approach for AC charging with 1000V DC charging based on existing SAE communication standards."

"The goals of J3068 include bringing a proven, mass produced three-phase charging coupler to North America, and establishing a low-cost, reliable communication and control protocol for AC with inherently high interoperability" said Jim McLaughlin, document sponsor and retired Mack Trucks electrical engineer. "High power AC charging has cost advantages in many use cases, and three-phase charging simplifies balancing of the power grid."
